Hi!
I have a small problem with Dave Gravel's raycast car, im using Newton 2.20.
If you setup the car on a perfect plane, and let it stop completely, the car will get "stuck'. I am NOT talking about the body going into auto-sleep (which I disabled for the car), I mean the wheels spins but the car gets not traction. This only happens if you willingly let it stop, as long as you move, everything is fine.
This does not happen in the SDK demo because there is always a slope and the car always moves.
I wonder if this isn't a special edge case that isn't handled... I can provide more info if needed.
